Why presumably? A wave function collapses when
a measurement is made, and this can certainly be
done through equipment which is clearly non-conscious.
Obviously at some point a conscious observer will
gather the data from that equipment, but unless we
are willing to assert that the record of that data is itself
in an indeterminate state prior to the observation (in
which case we have uncertainty operating at a very
gross mechnical scale!), this would argue that
consciousness not only interacts with nature, but that
it can do so by reaching into the past. I think there
may be some serious problems with that, to say the
least.

"certainly"? hmmmm.....

That is the convenional view, in QM.
Schrodinger's cat...
It is also the problem Von Neuman grappled with:
where does the wave function collapse occur?
Suppose we monitor electron scattering - does
the 'observation' occur at the sensor, tape, or
human brain? It's indeterminable; thus
metaphysics, not physics...

this would argue that consciousness not only
interacts with nature, but that
it can do so by reaching into the past.

You're behind the curve, Bob.
According to QM, cause/effect are not temporally
related. This has been verified, in the lab.
I refer you to the 'delayed choice' experiments,
where effect precedes cause!
It is even possible, in theory, to claim that we
created the Big Bang, by observing it, 15 billion
years later...

I think there may be some serious problems with
that, to say the least.

I think you need to do some research
into the metaphysics of QM... mind bending,
to say the last. John Gribbin's books are good.

Depends on how you define "consciousness." Hagelin defines consciousness
in Vedic terms: Observer, observed and process of observation, and shows
that these are the core of Quantum theory.
http://www.slac.stanford.edu/spires/find/hep/www?key=1535870
http://ccdb4fs.kek.jp/cgi-bin/img/allpdf?198912227
IN fact, using Vedic cosmology to guide him, Hagelin performed the
initial tweaks to Nanapolus's Flipped SU(5) theory, and found that the
tweaks made the theory more robust from a Western scientific
perspective. Hagelin contacted Ellis of CERN who contacted Nanopolous,
and the three published quite a few papers on the subject over the years.

You've confused:
1. Macroscopic measurement of portions of the experimental
apparatus; with
2. Human consciousness.

No. You are confused, in your belief that they are separable.

The double-slit experiment will give the same result
regardless of whether there are any humans anywhere
nearby the equipment while the experiment runs.

"nearby" has nothing to do with it. The wave function
encompasses everything, everywhere, everytime. You
cannot separate observer from observed.

I assume you aren't going to start claiming that the mechanical photon
detectors themselves have a kind of "consciousness".

I won't.

Otherwise, do you somehow believe that these mysterious
powers that you attribute to human consciousness can act over
great distances?

Yes, somehow...

Or perhaps act backwards in time;

The most bizarre aspects of quantum theory have
been confirmed. Superluminal correlation, and
cause/effect time reversal, are real.

maybe you extend Schrodinger's Cat to say that the
double-slit experiment actually gives all outcomes, and
it is only when the human returns -- perhaps months
or years later -- that the various printouts assume their final
shape to give the right data.

Correct. That is what the theory says.
If you believe ortherwise, please provide cites.
Your common sense notions of sensible and absurd
are worthless, in this domain.
Quantum mechanics has never failed.
Schrodinger's Cat is the same as the double slit -
everything exists in a superposition of 'potentialities',
until we look. Schrodinger's intent is immaterial;
he ended as an old crank, pecking at the theory
he helped create.

Or maybe, just maybe, you ought to try to understand
Quantum Mechanics without appeal to human consciousness.

Uh, no.
This is what you need to do, if you think consciousness
matters to physics. You need to design some physics
experiment in a black box. Once it is running,
you can't look into the black box room. There will be two
of them. They are identical black boxes, except one has
a consciousness in it, and the other doesn't.

You need to design the physics experiment so
that the black box outputs a 0 if and only if there
is no consciousness in the room, and a 1 if and only
if there is a consciousness in the room.

It is not possible to design this physics experiment
such that the black box has different outcomes
depending on whether the human inside is conscious,
or a vegetable.

The glaring weakness of your argument is that you
haven't defined what consciousness is... how you
gonna know, whether you see it or not? i.e. if a
box emits '1', on what basis will you deny the
result? It's all a bit fuzzy, Don.
Anyhow, I can describe a germane experiment,
which has been performed:
The usual electron double slit apparatus.
Electrons are emitted from a cathode,
sequentially, where each electron is fired
after the previous one has struck the screen.
There is a detector at each slit, attached to a
recording device, which counts the number
detected.
case i) Both detectors are off (removed
entirely, if you wish).
Result: interference pattern, electrons
behave like waves.
case ii) Both detectors are operational.
Result: no interference pattern, electrons
behave like particles.
case iii) One detector on, the other off.
Result: same as case (ii)
Cogitate upon case (iii), particularly compared
to case (ii). I claim this satisfies your challenge -
it demonstrates some interaction between the
observer's mind, and nature. It cannot be
explained by "interaction between measuring
device and object".
Call it 'consciousness' or whatever, it's real...

Yes, I'm aware of all this.
But in none of the experimental setup do you have any human
consciousness playing any role.

Alas, you inadequately cogitated.
What is the difference between case (ii) and (iii)?
In (ii), every electron is detected. In (iii), only half
the electrons click - no interaction with the
apparatus - yet results are identical. Somehow they
are 'observed'. Where does the observation take
place? What causes the wave function to collapse
to an event?
Whenever the active detector fails to click, the
experimenter deduces (or assumes) the electron
traversed the other slit. Thus, the interaction
occurs in the observer's mind!

You'll get the same results as you just described, whether
or not any human is anywhere nearby when the experiment runs.

"nearby" doesn't matter. What does matter, is that
someone observes the result.

I claim this satisfies your challenge - it demonstrates some
interaction between the observer's mind, and nature.


But there was no "observer's mind" in your description of the
experimental setup.

There is. And it explains the results.
You cannot reject it as absurd, when it fits the facts,
and you cannot offer any other explanation.

electron is detected. In (iii), only half the electrons click - no
interaction with the apparatus - yet results are identical. Somehow they
are 'observed'. Where does the observation take place?

Yes, they're observed. By the photon detector. Not by human consciousness.

What causes the wave function to collapse to an event?

Nobody knows. There's a huge chain of physical events between the progress
of a single photon, and the final observation by a human being. It's the
height of intellectual laziness to just assume that human consciousness
MUST be the causal agent to make the wavefunction collapse.
The actual equations of quantum mechanics (the things that have been verified
to an amazing degree by experimental evidence) NEVER talk about ANY collapse
of the wavefunction.
Yet we "appear" to observe only definite outcomes. This is indeed a puzzle,
but saying "consciousness causes it" is only slightly less mystical than
saying "God causes it" when talking about any other phenomena.
It isn't a well-supported conclusion, nor does it carry much explanatory
power. And finally, it opens as many new, unresolved, questions as it
appears to close.

Whenever the active detector fails to click, the experimenter deduces (or
assumes) the electron traversed the other slit. Thus, the interaction
occurs in the observer's mind!

Even if the experimenter isn't in the room at the time, and doesn't return
to look at the results for decades.
In your theory, the room and equipment just sit there, in some odd
superposition state, until someone comes in to read the printouts.
Even better, it could just be the janitor coming by to empty the wastebaskets.
He's not aware of any quantum theory, doesn't have any idea what the machine
does, clearly isn't able to make any conclusion at all about electrons and
slits and paths. But yet, if this conscious janitor should happen to turn
over the printouts and take a look, that will cause the wavefunction to
collapse too? Who's making the deduction then?
Perhaps God did it. That's as useful an explanation as yours is.

You cannot reject it as absurd, when it fits the facts, and you cannot
offer any other explanation.

I can't prove that it's false, of course.
But it's certainly incomplete. Any number of new questions remain
unanswered. For example, can you even define when an entity has this
consciousness thing? You don't think cats or photon detectors have this
magic ability to collapse the QM wavefunction, but you think that adult human
physics researchers do. Well, at what point does the ability first show up?
Does an unfertilized human egg have it? An embryo? A newborn? A teenager?
Cats don't have it. Do chimps? What happened to the universe before modern
humans arose, only a few million years ago? How do you reconcile this theory
with the other scientific fields like cosmology, or geology, or evolutionary
biology? They certainly posit that when the dinosaurs walked the earth 65
million years ago, that the earth behaved then much like it does now. The
dinosaurs weren't wandering around in some bizarre superpositions of
macroscopic quantum states, were they? Seriously, how do you reconcile your
theory with ANYTHING else known about the universe in other fields?
Meanwhile, there are plenty of alternate explanations, which don't require
a special role for consciousness.
For one, there might be something about exporting results up to
"macroscopically" significant sizes. Nobody knows what size would matter,
or why, but it might be that after a certain scale, superpositions collapse
to definite outcomes.
Or it might be that there never is a collapse. In the many-world
interpretation of QM, all the outcomes occur simultaneously.
The one thing we know, is that physics is far from PROVING that human
consciousness MUST be special (and thus that Strong AI is doomed to failure).

What is it that you are trying to do here? Are you trying
to PROVE a particular interpretation of quantum mechanics?
I hope you realize that's impossible and self-defeating.

There are several other interpretations of QM that are as equally
valid as the one you seem to be trying to "prove" to us here.

I personally subscribe to the Quantum Decoherence Interpretation,
since you dont have to bother with ontological questions and its
easily shown how it works on a chalkboard. It also contains no
references to "observesr" or "consciousness"
http://en.wikipedia.org/wiki/Quantum_decoherence

How does it explain the double slit experiment?

I can talk at length about various interpretations of quantum
mechanics and their particular plusses and minuses. (If you are
interested).

Be my guest...

There is no double-slit experiment for electrons.

uhhhhhhhhhh........

You read about that on some website.

Yeah, Volume 3 of Feynman's 1963 website...

The wave properties of electrons are determined
by some completely different experiment than
a diffraction grating.

So what? That's a thought experiment. There has never been a
double-slit experiment carried out PHYSICALLY on electrons. (You can't
even do it because of the de broglie wavelength.) They use these
wires called an Electron Biprism.

There's another consideration... in quantum
mechanics, the observer occupies a special
place - the wave function cannot collapse
(to a particular event)without one. But
'observer' is vague... presumably, it means
consciousness. Hence, consciousness has
some attribute whch interacts with nature.

Ah, but if we accept the many worlds interpretation of QM (as many have
been doing), you don't need a collapse of the wave function.
